Abstract: A method of preparing an enhanced oil recovery composition is described. The method includes carbonizing a biomass waste material to provide carbon microparticles. The method includes functionalizing the carbon microparticles through an acid treatment such that the carbon microparticles have a hydrophilic surface. The method further includes grinding the carbon microparticles to provide carbon nanoparticles, where the carbon nanoparticles have a hydrophilic surface and a hydrophobic surface. A method of enhanced oil recovery is also described.
